, Ahousing34 provided'for enclosing the bearing 19,is of substantially the same construction as the housing25 excepty that the housing 34 is at its inward end provided with a longitudinally extending cylindrical ange 35 Awhich iitsfover' the cylindrical portion 36 of the beveled pinion 10 and encloses an end thrust bearing washer 37 which is positioned between the end face of the beveled pinion 10 and a bearing plate 38 housed within the cylindrical narige 3,5 Vand engaging the end face 39 of the housing 34'. lThe housing 34 is at its opposite end provided with a closing cap 40 which is secured to thehousing 34`in the same manner as the end'plate-Z'L is 2v of the base 1; f "Means aref-provided for flocking thei pinion shaft9 to hold the rotary table 6 from rotation preferably of the following construction:

Mounted on the shaft 9 between the housings 25' and 34 and keyedthereto, as indicated atv45,

isa lock ring'fio. The lock ring 46 is provided arounditsper'ipher'y with a plurality of detents 47 into which locking pawls 48 are adaptedto nt. The locking' pawls 48 are pivotally mounted on pins 49 vwhich pass through and are secured to standards 50 preferably lcast integral with the ,longitudinal'exte'nding portion 2 ofy the base 1.

In lthe modified form of Athis invention` illustrated in Figures4 and 5, a `pair of spaced bearing housings are provided Afor the pinion shaft 9a and the supporting bearingsthereoi for a rotary machine in a manner similar to that disclosed by Figures 1, -2-`an`d 3 oi this application.

` In Figures A4 and 5 'onlyfone of such bearing -housings-are disclosed and that is the bearing housing corresponding to the bearing housing 34 of the machine disclosed in' Figures l to13 inclusive. A second spaced bearing housing'similar in construction to the hearing housing' 25 is also providedv spaced lon the' pinion shaft as in the case of the iirst modication of thisl invention. In this modification of the invention the two bearing housings are substantially 'of the same form and are spaced' along the shaiti)a .of the rotary machine to enclose theb'earings 13 and 19. Each bearing housing includes a `form of a'casting substantially cylindrical in form `and of substantially the same-internal construction as `thebearing.housings 25 and 34 and differs from the bearing housings 25v and V`34 Vonly inthe r form ofV bridge construction 5 -pby`rneans of which the bearingI housings are secured in position'to' the outwardly extending `portion`2 of the base 1'.' v v The vbridge construction includes an outward- 'ofA a f one-piece self -contained vly extending web casting which tscloselybetween a pair of upstanding standards 51a formed on the outwardly extending portion 2 of the base 1. The bridge construction 50a is thus, byv means ofthe standards, centralized axially between the standards 51aso that vthe n. pinion shaft 9PL will be accurately radially located in relation' to th rotary table 6 of the rotary 4machine.

In order to locate the shaft!)a in a correct horizontalplane, and to hold the same in correct position, caps' 52a are provided for the standard 51a and aresecured to the standard 512L by means of bolts 53a. The vertical position of the' caps 52@A is adjusted and determined by means of lshirns 54EL interposedV between the'upper surface of the standards 51EL and the caps 52%. The caps 52a are formed integral with 'the bridge 50.a and the placing of shims 54a in position determines the vertical position oi" the shaft 9a.

In order to hold the housings, land consequently the shaft, 92"` and the pinion carried thereby,

away from the rotary table 6, `keys 55e are provided which nt inkeyways 56a formed between f the bridge 50ad and standards 51a. The keys 55a are tapped as indicated at. 57@L 'to' receive abolt or other threaded instrumentto permit the withdrawal. of the keys whenit is desiredto remove the unitary pinion assembly provided.

Having fully described our invention, it is to itedto the detailsy herein set forth, but our invention'is of the full scope of the appended claims.

We claim: 1.y In a bearingstructure,

2. In a bearing mounting, the combination of a one-piece self-contained bearing housing havhe understood that we do not wish to be lim-r the combination bearing housing ing laterallyextending rarms, each having anv inverted L-shaped yrecess providing rhorizontal 'and vertical'surfaces, a supporting basehaving two spaced standards .extending upwardly from saidbase beyond the horizontal centerline of EDWARD'TIMBS. f -I ,DANrEL `wenn wAnTERs,
